Abstract

L'INVENTION CONCERNE UN ROTOR POUR POMPES CENTRIFUGES ET AXIALES. CE ROTOR COMPORTE UNE AUBE 1 DONT L'EPAISSEUR EST VARIABLE ET RESULTE EN UN CONDUIT DONT LA SECTION VARIE EN DIMINUANT LEGEREMENT DU BORD ANTERIEUR 2 DE L'AUBE VERS LE BORD DE SORTIE 3. L'INVENTION S'APPLIQUE AUX POMPES POUR LES EAUX USEES.THE INVENTION CONCERNS A ROTOR FOR CENTRIFUGAL AND AXIAL PUMPS. THIS ROTOR INCLUDES A VANE 1 WHOSE THICKNESS IS VARIABLE AND RESULTS IN A DUCT WHOSE SECTION VARIED BY SLIGHTLY DECREASING FROM THE FRONT EDGE 2 OF THE VANE TO THE EXIT EDGE 3. THE INVENTION APPLIES TO PUMPS FOR WATER USEES.
